Abstract

The invention discloses a high temperature resistant casting coating, relating to the technical field of casting. The casting coating is prepared from the following raw materials in parts by weight: 45-60 parts of hollow ceramic powder, 5-8 parts of sodium silicate, 2-4 parts of bentonite, 2-3 parts of sepiolite, 3-5 parts of bauxite, 1-2 parts of quartz powder, 0.1-0.2 part of oxidant, 0.01-0.05 part of preservative, 0.05-0.2 part of wetting agent, 0.1-0.2 part of defoaming agent and 50-60 parts of deionized water. The problems that the existing metal mold casting coatings have poorer high temperature resistance and adhesion properties are solved by adopting the high temperature resistant casting coating.

Description

High temperature resistant cast paint
Technical field
The present invention relates to casting technology field, especially a kind of high temperature resistant cast paint.
Background technology
Permanent mold casting is poured in metal die by liquid metals, and to obtain a kind of casting method of foundry goods, it is also known as diecasting or permanent mold casting, is the technology grown up in recent years.The pouring temperature of metal mold and speed are all high than sand mold, fast, because will produce the defect such as underpriming, cold shut when pouring temperature is low, speed is slow.During permanent mold casting, all can apply coating at mold cavity surface, coating can be protected metal mold from thermal shock during cast, washes away and wear and tear, and can regulate the cooling velocity of foundry goods, improve the surface quality of foundry goods, when taking out foundry goods, can prevent casting mold from wearing and tearing.Resistance to elevated temperatures and the adhesion property of existing metal-type casting coating are poor, cannot meet the mass production requirement of heavy castings.
Summary of the invention
The object of this invention is to provide a kind of high temperature resistant cast paint, it can solve existing metal-type casting coating resistance to elevated temperatures and the poor problem of adhesion property.
In order to solve the problem, the technical solution used in the present invention is: a kind of high temperature resistant cast paint is made up of the raw material of following masses number: hollow ceramic powder 45-60 part, waterglass 5-8 part, bentonite 2-4 part, sepiolite 2-3 part, bauxite 3-5 part, silica flour 1-2, oxidant 0.1-0.2, anticorrisive agent 0.01-0.05, wetting agent 0.05-0.2, defoamer 0.1-0.2, deionized water 50-60.
In the technical scheme of above-mentioned high temperature resistant cast paint, technical scheme can also be more specifically: 52 parts, hollow ceramic powder, waterglass 6 parts, bentonite 3 parts, sepiolite 3 parts, bauxite 4 parts, silica flour 1.5, oxidant 0.15, anticorrisive agent 0.02, wetting agent 0.1, defoamer 0.15, deionized water 55.
Further, the average grain diameter of hollow ceramic powder is 45-80um.
Further, oxidant be in chromium oxide and iron oxide one or both.
Owing to have employed technique scheme, the present invention compared with prior art has following beneficial effect: have excellent resistance to elevated temperatures, tack is high, resistance to erosion, good air permeability, can meet the mass production of heavy castings, improves the surface quality of foundry goods; High temperature resistantly reach more than 1750 DEG C, heat insulation suppression efficiency reaches about 90%, coating abrasion performance more than 0.6, and dope viscosity is 40s.
